PROBLEM TO BE SOLVED: To protect a two-folded section from being broken by the weight or edges of the stored article when the article is stored in the two-folded bag and prevent the generation of creases on the bag between a hot roller and a back-up roller of a toner fixing section when the printing by a non-impact printer of the electronic photograph method is carried out. SOLUTION: A heat-sensitive paste 10 generating bonding force by heat or a pressure-sensitive past 10 generating bonding force by pressure is applied on the inner face of a two-folded section 8 of the two-folded bag 2, and when the bag 2 is passed through between the hot roller and the back-up roller of the printer, the shift between the front side paper and a back side paper is generated by the difference of the friction force, and then the two-folded section is bonded by the heat-sensitive paste or the pressure-sensitive paste to increase the strength of the two-folded section.
